Blowing Dust Test Chamber

Name: Blowing Dust Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

As a leader in environmental simulation chamber, LIB Industry blowing dust test chamber complies with MIL STD 810 standard. The MIL STD 810H standard is designed to ensure the reliable operation of military equipment in a variety of harsh sand and dust environments. The blowing dust test chamber blows the dust into the workroom to form a dust environment with high wind speeds 1.5-8.9m/s and 18.0-29.0m/s respectively for dust and sand.

Model: DIM-1000

Standard: MIL-STD-810G

Features and Benefits of Blowing Dust Test Chamber

1. The workroom, air duct, etc., use strong and corrosion-resistant SUS304 to resist the wear and erosion of sand and dust, and choose high-quality double-layer rubber seals to prevent sand and dust leakage and ensure a stable dust environment inside the blowing dust test chamber.

2. Accurately control the amount and speed of dust injection. 10.7±7g/ m³ blowing dust and

0.18+0.2g/m³; 1.1+0.3g/m³; 2.2+0.5g/m³ blowing sand can be injected to simulate a variety of different dust environments.

3. The sand particles spin at high speed in the workshop and the pipeline, and friction with the inner wall of the pipeline to generate a lot of heat. Set up a tank outside the pipe to allow water to flow around the pipe and absorb the heat from the pipe.

4. The dust cycle is to collect the falling dust through the bottom funnel-shaped structure, and after filtering through the mesh screen of the collection port, the fan is inhaled again and lifted to the upper space of the test chamber to achieve the repeated recycling of dust.

Configuration of Blowing Dust Test Chamber

① Workroom	The workroom is equipped with temperature probe, wind speed probe, concentration probe which ensure accurate data and timely return to the controller. Dust is blown in from the left side of the workroom, and the duct circulates counterclockwise. The workroom is equipped with lighting and the observation window is equipped with wiper to facilitate observing test.
② Centrifugal fan	The sand is inhaled and sprayed through the pipe into the workroom, so that the sand is blown over the surface of the test sample. The centrifugal fan is driven by the pump pulley⑥.
③ Heating tube	Heat the air inside the chamber to prevent sand and dust from sticking together due to humidity. And provide the heat needed for the workroom.
④ Water tank	Provide water for air duct cooling.
⑥ Pump pully	Connect and drive the pump to provide power for the circulation and transport of dust.
⑦ Dust inlet	The test dust is introduced into the test chamber.
⑧ Dust return port	The excess sand and dust generated during the test or the worn sand and dust particles are discharged from the test chamber.
